Arithmetic Logical Unit
The part of a [[CPU]] that does all the arithmetic. Basically, it can only do four things: Add one, subtract one, shift a register's content 1 bit to the left or to the right (which is equivalent to division and multiplication by 2), but it does so really, really fast...

BYOD is an acronym for Bring Your Own Device or, as often is the case, Be Your Own Demise.
Here I'll try to present some factors that might help you decide on a suitable device for school use.
Not all computers are equally suited for the purpose of being lugged around for school use, and they shouldn't be. If all devices were to cater for every need by every student and every application and task that we do in school then the devices would become prohibitively expensive, heavy and power hungry. So we need to make some sacrifices to reach a workable compromise.
Renmark High School provides desktop computers in computer rooms for all computationally heavy use. This includes working with high-end graphics programs, graphics rendering of 3D work, Computer Aided Design and much more. All the things that can't reasonably be expected to work on a cheap laptop with limited screen area and often just a touchpad for cursor navigation. So don't worry about buying hardware for those purposes.
What a BYO device needs to do well is the 'bread-and-butter' stuff. It needs to be able to run the 10% of applications that are used for 90% of the work. Text manipulation, spreadsheets, slide presentations, browsing the web and be able to render HTML5 in a meaningful way.
A BYO device also needs to cater for the user's habits and abilities. If your eyesight is not good then a small screen will either be hard to read or will only present a very limited amount of information in every view. If you prefer a fast computer with good gaming capabilities then the power consumption goes through the roof and your batteries will not be able to last a school day. An Intel i7 processor is able to control more internal memory than an i5, giving you the option to have more applications running at a time (and faster) but it uses about twice as much power doing so.
A dedicated school laptop can be quite cheap. A grunty gaming laptop is not.
Even cheap laptops can have 8-10 hours battery life. High-end laptops rarely exceed 2-4 hours.
A cheap laptop will probably not do everything you want to do outside school hours, consider getting another laptop or desktop for that.
Tablets, iPads, Chrome or Android tablets are fine for school. They both have apps available for almost all purposes that are expected of BYO laptops. The invokeable keypads are probably too slow for serious writing and they take up a lot of the app's viewport when you're typing (tapping), consider getting a good quality Bluetooth connected keyboard with the tablet, these can be had for as little as ~AUD25 and add tremendous value to your typing experience. Screens smaller than 9" (grab a sheet of A4 printer paper, fold it in half on the short side and draw a 1cm border on the folder paper. That's about the size of a 9" screen on a tablet) are often hard to read or has very little info in the views.
MacBooks are great. They have a good trade-off between speed and battery life and will do most of what is expected right out of the box. Among the downsides are: initial cost, cost of peripherals, lack of support and various quirks in applications that weren't natively made for MacOS but have been 'ported' from the Windows versions. In short, they don't always work as expected.
ChromeBooks are the cheapest of the laptop range. They have a tight integration with Google's G-Suite for Education (which we have installed and working at [[RHS]]) providing seamless workings between all apps from Google and access to a myriad of other SaaS. The newer Chromebooks integrate with the Android Play Store and can run all Android apps as well as the ChromeOS apps. Many Chromebooks are cheap because their screens have quite a low resolution, making less room for information and shortcuts, but the higher resolution ones are still quite affordable.
[[Storage and memory]] are two other factors that have a huge impact on the user experience of a computer, be it a laptop, desktop, tablet or phone. When storage runs full no more applications can be installed and some [[operating systems]] will stop working as well. Too little memory will impact on the number of applications that can run simultaneously, eventually forcing you to close one thing in order to start another. Low memory also forces most [[operating systems]] to use storage for short term memory, slowing the computer to a grinding halt because storage works thousands of times slower than memory.
A practical minimum of storage for a laptop, be it Windows or MacOS based, is 128Gb of [[harddisk]], the bigger the better. Chromebooks, iPads, Android tablets rarely have a harddisk but rely instead on built-in memory chips ([[RAM]]) and are usually equipped with enough for the purpose. Again, the more the better, 8Gb is probably a practical minimum.
Memory for laptops should not be less than 4Gb, as this is the minimum specified by Microsoft (for Windows) and Apple (for MacOS). Laptops run significantly faster when upped from 4Gb to 8Gb whilst there is less improvement by the next doubling to 16Gb. More memory lets you have more applications running simultaneously.

As always.... Try fixing it yourself!
On this wiki you'll find help, [[howtos]] and trouble shooting hints for helping yourself navigate the murky waters of IT in a school environment.
I'll be updating on a semi-irregular basis (meaning: when I feel like it and when I have something to contribute) and all changes can be monitored by looking at the Timeline on the right...
If you get stuck then you can always drop in and ask (or you can email samps@renmarkhigh.com) and if you want to avoid disappointment you can book an appointment with the tech on duty.
10 minute timeslots are available every day between 11 and 12, for students only!! Staff members have plenty of other options for contacting IT services...
You can access the tech's calendar [[here|https://calendar.google.com/calendar/selfsched?sstoken=UUoya2I2WmMySGM0fGRlZmF1bHR8NWRmZjE5N2YyMDFhYjRjOWM0YzMyZDY5YzBjZjBmMDU]].
If prompted, log in with your @renmarkhigh.com email address and choose a time that suits you (if you hover over the available timeslots they will show you when they start and finish).
Don't forget to log out of Google when you're done and return to this page using CTRL+TAB buttons...
You don't need an appointment for simple things that take no time to fix but I recommend that you book if it's more complicated, like: connecting your own laptop to the school network, finding lost files on our servers, etc...

Daymap has been updated to v9.7.9
New funtionality and a lot of bug-fixes
--------------------------------
Did you know...??
It is a REALLY GOOD IDEA™ to reboot your Windows computer a few times a week.
Microsoft usually issue updates on Tuesdays and in the time between your computer downloading and installing these and the point where you restart it the computer is not always as stable as it could be, which can explain many minor and major hickups.... so just restart it, or shut it down completely over night.

Central Processing Unit
The 'brain' in a computer. This is where all computation is done, mostly by the CPU's [[ALU]]s, with some assistance from the attached [[registers]]

Get a certificate by clicking [[this link|https://unplugd.com/certs/0794-MWG-CA.cer]] and, if asked, choose the option to 'Save' the file.
Then install it in accordance with these [[instructions|Install an Internet Access Certificate]]

A laptop offered by Google; with tight integration to the G-Suite apps and management framework.

School printers are meant to be connected during the login process.
If, for whatever reason, this doesn't happen then you can manually attach a printer after you have logged on.
Here's how to do it on Windows 10:
* Click the Windows 'Start' button and type 'printers'
* Click on 'Devices and Printers'
* Click on the 'Add Printer' button
* If the printer you want is listed then click on it and then click 'Next' and 'Finish', you're done!
* If the printer is NOT listed then click the option saying: 'The printer I want is not listed'
* If you are on a school computer then on the next screen choose the second option: 'Select a shared printer by name' and type \\10.72.20.52\ in the field below and hot the 'Browse' button. A list of school printers will be displayed for you to choose from. Click one, click 'Next', 'Finish' Done!
* If your computer is not a member of the RHS domain (a school computer) then you should choose the third option instead: 'Add a printer using TCP/IP' and on the form that comes up when you click 'Next' you type the address og the printer you want to attach in the field called: 'Hostname or IP address' and click 'Next' and 'Finish'
The addresses of our printers are as follows:
|!Printer name|!Location|!Ip address|
|D20|D20 Computer Room|10.72.20.57|

[[WIP]]
This tiddler is written as a dual-strand thing that is meant to cover both Mac and Windows (sorry, to those using Linux... but you already know what you're doing!).
The reason that this tiddler is in this [[category|future fidgetry]] is that it is far from finished... if you choose to go with it that's fine.... but don't come running to me for a fix if it blows your... .. bleh... whatever!
I will state examples explicitly for Mac and solely for Windows whereever it is necessary to discern between the two...
----------------------
Having access to everything you create whenever and whereever you like has been built into the Chrome OS that runs on Chromebooks since day 1.
Now you can get that functionality on Windows and Mac as well.

This tiddler is written for Windows 10. If you're one of the unfortunates with a MacBook then have a read [[here|instead]]
Start your lappy and log in or whatever you normally do...
Find the wireless icon in the notification area (lower right-hand part of your screen) and click once on it. From the list that pops up you choose 'RHSRADIUS' and click the 'Connect' button.
When your lappy asks for username and password you enter:
<pre>
User : rhs\%your network login name%
Password : %the password for your network login%
</pre>

If your computer has lost connection to network drive, which can happen when either computer or the server that hosts the network drive share loses connection to the network, then you can re-attach it without having to log off and on again.
Here's how:
1. Click on the Windows Start button and choose 'My Computer' (Win7 and earlier) or type 'File Explorer' (Win10) to open the Windows File Explorer
2. Click to highlight 'This PC' or 'My Computer' then click on 'Map Network Drive'
[img[https://unplugd.com/RHS-IT-graphics/explor1.png]]
and a dialogue is presented:
[img[https://unplugd.com/RHS-IT-graphics/explor2.png]]
where you choose a drive letter and fill in the name of the server and the share that you want to attach as a network drive. In this instance drive P: is connected to the 'public' share on the server called 10.72.20.40
3. Click on 'Finish'

HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It is the fifth and current major version of the HTML standard.

This tiddler is written for Windows 10.
If your laptop is a ~MacBook, Chromebook, Android phone or tablet or an iPhone then read [[this|chromacandiphone]] instead. If you're using an older version of Windows then you're probably fully capable of translating the instructions to suit your needs.
Here goes...
1. Power up your lappy.
2. Log on to Windows (or don't if you normally don't)... just get to the bit where there's a desktop with icons and you can start stuff...
3.Click (or tap) on the icon in the Notification Area (lower right-hand side of your screen (unless you've moved it)) that looks like a dot with three concentric quarter circles radiating from the dot in a North-Westerly direction; and choose the network called 'RHSRADIUS'.
4. Tick the box saying: "Connect automatically' and then hit the 'Connect' button.
5. In the dialogue that's displayed, enter RHS\%your network logon name% (where %your network logon name% is probably your firstname and lastname (without the %'s)) for username and the password that you normally use to log on to our school network. So... if your name is Bob Dylan then you write
{{{RHS\bob dylan}}} (that's a 'backslash' between RHS and your name, it lives just above the Enter button on a standard US layout keyboard)
and whatever your normal school computer password is.
Hit 'OK'.
You should now be connected to the internal school wireless network.
To get access to the stuff that matters (Internet, doh!) you need to install a cryptographic certificate to allow our filtering machine to open all packets of information that go in or out of our network for inspection (that might sound intrusive and you don't have to do it, but if you don't you won't be getting any Internet access)
To install a certificate I suggest you start [[here|Certificate for encrypted access through the school web filter]]

These instructions are aimed at installing on Windows. I'll describe the process for Mac and IOS when I get around to it...
1. If you haven't already obtained a certificate I suggest you start [[here|Certificate for encrypted access through the school web filter]], else continue to point 2
2. Double click on the downloaded certificate file and click on 'open', 'allow', 'continue' or whatever is needed in order to proceed..
3. When you have convinced Windows that you know what you're doing this window will pop up:
[img[https://unplugd.com/RHS-IT-graphics/shot1.png]]
4. Click the 'Install Certificate' button and a new window is shown:
[img[https://unplugd.com/RHS-IT-graphics/shot2.png]]
5. Tick the 'Local Machine' option and then the 'Next' button, yet another window is displayed:
[img[https://unplugd.com/RHS-IT-graphics/shot3.png]]
6. Choose the 'Place all certificates...' option and click the 'Browse' button, this tiny window is served:
[img[https://unplugd.com/RHS-IT-graphics/shot4.png]]
7. You highlight the 'Trusted Root Certification Authorities' option and click 'OK'. You are now returned to the previous window:
[img[https://unplugd.com/RHS-IT-graphics/shot5.png]]
8. Click the 'Next' button and expect to see this:
[img[https://unplugd.com/RHS-IT-graphics/shot6.png]]
9. Click 'Finish' and you should be greeted with a sign like this:
[img[https://unplugd.com/RHS-IT-graphics/shot7.png]]
After which you are returned to the first of the windows:
[img[https://unplugd.com/RHS-IT-graphics/shot1.png]]
where you click 'OK'
10. Restart your web browser.

Random Access Memory
Memory accessibe to the [[CPU]] for operations too large to be handled in its registers...

Short for Renmark High School

To provide a little bit of spam protection all mailto email links on this wiki have been injected with some capital letters that need to be removed before clicking 'Send'

You can easily resset your Google/Chromebook password yourself...
* Log on to a school Windows computer.
* Hit Ctrl+Alt+Del simultaneously and choose 'Change Password'.
* Enter your old (current) password
* Enter a new password, with upper AND lower case letters AND a number AND minimum 8 characters in length with NO part of your name in it...
* Enter the new password again to confirm and rule out spelling mistakes
* Click 'OK'
Changing your Windows (school network) password also changes your Chromebook (Google Apps) password so the two are kept in sync...

Storage is the place where a computer filesystem stores user data, system data and applications in order to be able to retrieve data at any time in the future.
Memory is 'owned' by the CPU and used for short-term, volatile storage of data currently being processed. Memory is not directly accessible by users or the file system and is cleared when the computer is powered down.

Work In Progress
Don't take [[WIP]] tiddlers/ideas for gospel. They are, by nature, volatile, sensitive to political decisions, may be deprecated/ridiculed/overridden at any time... they may also prove to be the harbingers of great new stuff and functionality, so don't write them off yet....

NET::ERR_CERT_COMMON_NAME_INVALID
NET::ERR_CERT_COMMON_NAME_INVALID an error reported by Google Chrome Browser when accessing certain sites
Affects Chrome Browsers since version 58
Caused by a change in how Chrome Browser handles common names for parts of websites that aren’t covered by own certificate.
The fix is to override this behaviour by changing a key in your computers Registry.
Easiest way to do that is to download this [[registry hack|https://unplugd.com/RHS-IT-files/EnableCommonNameFallbackForLocalAnchors.reg]] and executing it by double-clicking on the downloaded file. Then restart your browser.
On a Mac you can fix it by [[opening the Terminal]] and pasting this line to it:
{{{defaults write com.google.Chrome EnableCommonNameFallbackForLocalAnchors -bool true}}}
then hit the return button and restart the Chrome Browser

On a Mac... Open 'Finder' (usually the first icon on the dock) and type terminal in the search box at the top of the Finder window.
The Terminal icon looks like this:
